Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit boards, in particular to a bending protection device for a flexible circuit board. Background Art

[0002] A flexible circuit board is a printed circuit board made of a flexible insulating substrate. It has many advantages that rigid printed circuit boards do not have, such as being able to bend, wind, and fold freely, and being able to withstand millions of dynamic bending cycles without damaging the wires. Existing protective devices cannot be adjusted, making it impossible to install them on flexible circuit boards of different lengths or thicknesses. The scope of application is relatively limited and cannot meet usage requirements.

[0003] For example, the publication number CN202023169411.3 discloses "A flexible circuit board with a bending protection structure", which is equipped with an L-shaped block, a strip spring sheet, a perforation, a rectangular groove, a rectangular rod, a rectangular inner tube, a first screw, a first knob, a pressure block, an anti-slip rubber block, a circular rod, a rectangular pressure rod, a rubber sheet, a second screw and a second knob to adjust the upper and lower heights of the pressure block to achieve compression and fixation, which can be used for pressing flexible circuit board bodies of different thicknesses.

[0004] During the bending process of the flexible circuit board, a large number of control components are arranged on its surface. The existing flexible circuit board has a relatively poor protection effect on the control components. Therefore, when the flexible circuit board is bent, the control components are often bent together, thereby affecting the electrical performance of the flexible circuit board. Utility Model Content
